Can't boot High Sierra when using Intel RST

[llonca13]

@RehabMan so to confirm:
1)Clean install High Sierra (AFS):
SATA-RAID-Unsupported.kext doesnt work to boot OSX bootdrive when bios in (intel) RAID mode, AHCI works.
2)Clean install Sierra, update to High Sierra (avoiding conversion to AFS, staying on HFS+) :
Kext works, OSX boots from SATA (non Raid member) drive while BIOS is set to RAID mode

Guess the variable making the problem is AFS.
Sorry once again I have no logs to help you troubleshoot, and thanks a million for this kext
Saved me alot of trouble (changin from raid to ahci all the time, even ruined my raid0 array one time )
Thanks

The kext works fine.
You must have made a mistake or you have some other problem not related to the kext.

What's your CSM setting on BIOS.
In CSM setting, boot storage option must be contained legacy mode.
if not, osx makes a kernel panic.
